Traditionally, the surgical management of acute type B aortic dissections was reserved for patients with signs of malperfusion, rapid expansion, retrograde dissection or rupture. The adjunct of endovascular techniques has brought a paradigm shift, leaning towards preventing long term dissection complications. Multiple risk factors have been proposed to identify patients at risk for long term aortic complications. The patients, who are offered a prophylactic endovascular therapy for uncomplicated aortic dissection, should be selected carefully, and offered intervention by an experienced team in a high-volume center. (This is a review article based on the invited lecture of the 57th Annual Meeting of Japanese College of Angiology.).
